Mission Control Flight Director appointments

NASA has named nine new flight directors who will join a unique group of individuals that lead human space flights from Mission Control, Houston.

It is the second largest such class ever selected, and brings to 30 the number of active Space Shuttle and International Space Station flight directors. The new class includes the first African-American and the first two Hispanics to be assigned as flight directors, and adds three women to the four already leading Mission Control teams.

"This is one of the most diverse classes of flight directors we've ever selected," said Jeff Hanley, chief of the Flight Director Office. "These nine individuals represent the depth of talent we have among Space Shuttle and International Space Station flight controllers, as well as the changing nature of the flight control cadre. Since Christopher Kraft became the first flight director more than 40 years ago, only 58 men and women have had the privilege to guide U.S. human space flights."

Leading a team of flight controllers, support personnel and engineering experts, a flight director has the overall responsibility to manage and carry out Space Shuttle flights and International Space Station expeditions. A flight director also leads and orchestrates planning and integration activities with flight controllers, payload customers, International Space Station partners and others. The selection process began in August 2004.

"There were many outstanding people to consider -- both civil servants and contractors -- in the Mission Operations Directorate, the Johnson Space Center and NASA," Hanley added. "These are just a few of the dedicated people who applied, but there will be more opportunities for the rest on the horizon as we meet the challenges of the Vision for Space Exploration."

All of the nine new flight directors have served as flight controllers, either for NASA or its contractors. The flight director class of 2000 was the largest class with 10 members. The largest before that was the 1983 class with eight members.
